Abstract

Digital maps carry along its geodata information such as coordinate that is
important in one particular topographic and thematic map. These geodatas are meaningful
especially in military field. Since the maps carry along this information, its makes the
size of the images is too big. The bigger size, the bigger storage is required to allocate the
image file. It also can cause longer loading time. These conditions make it did not
suitable to be applied in image catalogue approach via internet environment. With
compression techniques, the image size can be reduced and the quality of the image is
still guaranteed without much changes. This report is paying attention to one of the image
compression technique using wavelet technology. Wavelet technology is much batter
than any other image compression technique nowadays. As a result, the compressed
images applied to a system called Map Online that used Internet-based Image Catalogue
approach. This system allowed user to buy map online. User also can download the maps
that had been bought besides using the searching the map. Map searching is based on
several meaningful keywords. As a result, this system is expected to be used by Jabatan
Ukur dan Pemetaan Malaysia (JUPEM) in order to make the organization vision is
implemented.
